“…The contact pressure (74KN/m 2 ) between the rotor and brake pads with constant speed and time led to the variation in friction pad samples produced. The trend was reported by [13][14]. The minimum produced brake pad (S3122) wear was 3.17g while that of commercial brake pad was 3.92g as shown in Fig.…”

In the present research, organic materials (coconut fruit fibres CFF and oyster sea shells OSS) were used as a substitute for asbestos materials. The waste CFF and OSS were washed, crushed, grounded, and sieved to different sizes. The sieved CFF and OSS as reinforcement materials were prepared in three different levels, K1, K2, and K3, with addictive such as phenolic resin, graphite, copper, and hardener. Level K1 has 50% of OSS and 0% of CFF, K2 has 50% of CFF and 50% of OSS, while K3 has 50% of CFF and 0% of OSS. The prepared levels were moulded in clean metal moulding plates up to twenty-seven (27) runs using the Box Behnken Design technic of four factors and three levels. The 27 produced brake pads and commercial brake pad CBP were tested in a laboratory to determine their characterization, such as; thermal conductivity, thermos gravimetric analysis (TGA) and wear rate. The characterization of the produced brake pad has a related standard brake pad coefficient of friction of 0.3 – 0.45 while that of produced brake pad PBP has the lowest TGA of S3232 - 25.44% than CBP 41.90% and PBP of S3122 has the lowest wear rate of 3.17 than CBP 3.92g. From the evaluation, the PBP were superior and performed best in braking application.

“…The reductions in particle size brought about the reduction of mechanical failure in nucleation sites and increased strength of interfacial closeness. Hence, from the lower compressive loads, the brake pad samples with larger grain sizes fail owing to the collective influence of feebler ties, transmission sites, and more crack instigation, as reported by Ossia C.V. et [21,22]. From the graph, the highest compressive strength of the developed brake pad was 2.58Mpa greater than that of commercial brake pad 2.48Mpa; which implies low wear and tears in the brake pad produced and capable of withstanding mechanical failure than commercial brake pad.…”

Coconut Fruit Fiber, CFF, and Oyster Sea Shells, OSS were gathered from the waste peel and suspended in a solution of sodium hydroxide (NaOH) for about 12h in other to eliminate unwanted remnants. Dried CFF and OSS were grounded to powder using an electric grounding machine. Thereafter sieved to 75, 125, and 175µm grain sizes. The based materials, CFF and OSS were prepared into organic-based brake pads by compressive molding with different formulations of base materials, epoxy resin, hardener, graphite friction modifiers, and copper chips. A commercially bought brake pad was used for evaluation in this research. The characterization of the brake pad produced is mostly influenced by molding pressure and grain sizes, respectively. Hence, the density, hardness, tensile strength, and compressive strength values were reduced with a rise in grain sizes. In conclusion, the ideal values of all responses fall within the normal desires of brake pads as they matched positively with commercial lining material. Thus, the characterization of the developed friction lining links suitably and is proficient in creating fewer sounds during the application of braking, owing to its high mechanical properties. Therefore, coconut fruit fibers and oyster sea shells can be a conceivable replacement for asbestos friction brake lining manufacture.

Asbestos has been a significant reinforcement material in producing automobile friction components due to its physical and mechanical properties. However, the replacement of asbestos and other toxic metals employed in producing conventional friction components has been called for due to health and environmental concerns. Research in this area has led to the development of more efficient non-asbestos-based organic friction materials for automobiles. In this study, recent progress in the manufacture of non-asbestos-based, eco-friendly automotive brake pads is reviewed. A thorough classification of conventional and non-conventional friction materials used in the development of brake pads is presented, and the production method and the roles of friction materials in the mechanical and tribological properties of the manufactured pads are discussed. The study shows that the performance of brake pads manufactured from plants, animals, or plants and animal materials (hybrid) varies depending on the physical, chemical and mechanical properties of the plants and animals.
